provide means whereby molten glass may be.

delivered directly from the furnace to the molds without the use ofladels or other manually operated instruments.

A further object of my invention is to provide glass drawing means ofsuch construction that in the event of any of the parts thereof becomingworn, damaged or burnt out, the same may be replaced quickly and easilyand at comparatively low cost.

A still further object of my invention is to provide means fordelivering molten glass directly from the furnace to the mold furthercharacterized by means for preventing the glass from becoming cooled orchilled until the glass has been actually delivered to the mold; theconstruction being such as to keep the glass discharge opening free from,frozen or chilled glass.

A still further object of my invention is to provide a device as thusbriefly character.

ized, provided with improved means for controlling the flow of moltenglass to the discharge port or opening.

A still further object of my invention is to provide means whereby whenmolten glass has been delivered to the mold, the string of glass issevered in such manner as to prevent the same being deflected from themold opening.

A still further object of my invention is to provide in a glass furnaceprovided with pool and discharge openings, an

therefrom is controlled to better center the same in relation to themold.

With these objects in view, together with others which will appear asthe description proceeds, my invention resides in a gathering pool orchamber in direct communication with molten glass within a furnace,flame'jets adjacent and' operating upon the glass in the said chamber, adischarge opening at one end of the chamber positioned preferably invertical alinement above the molds, means within the said chamber forcontrolling the flow of glass to the discharge opening or outlet, and apair of shears positioned with their cutting edges between the dischargeopening and the mold in order that the glass may be severed from thechamber when been delivered to the mold.

My invention further consists in a device as thus briefly describedwherein the several parts which form collectively the complete devicemay be quickly and easily separated a sufficient quantity has in orderthat, in the event of breakage, or 1 wearing or burning out of any ofthe parts, the same may be readily replaced at a comparatively low costMy invention still further consists in the arrangement of an improveddischarge nozzle in communication with the discharge opening or outlet,wherein the flowing glass may be delivered to the mold without danger ofthe same becoming deflected or spilled upon the edges of the mold.

My invention still further consists in the arrangement of a pair ofautomatically cooling vertically adjustable shears between the dischargeopening and the mold, the arrangement being such as to govern the shapeof the glass delivered to the mold.

y invention still further consists in the novel arrangement andcombination of parts, all as will be more fully described hereinafter,and more particularly referred to in the appended claims.

In the drawings forming a part of this specification, Figure 1represents a front view of a glass delivering or drawing apparatusconstructed in accordance with my invention, parts of the glasscontaining chamber being shown in section, Fig. 2 is a top plan view ofthe device illustrated in Fig. 1, Fig 3 is a longitudinal section takensubstantially upon the line 33 of Fig. 2, Fig. 4 is a plan view of theimproved glass cutting shears employed in carrying out my in vention;and Fig. 5 is a fragmentary section of a portion of a glass containingchamber showing a slightly modified form of the device.

Referring now more, particularly to the drawing 1 represents generally aglass furnace, which may be of any approved design, and which isprovided with a gatherside of the furnace wall, and which is adapted tocontain molten glass from the furnace. Detachably secured to the outerend .of the gathering pool or chamber 2, and communicating therewith, isa chamber portion 3. This chamber portion may be secured to thegathering pool in any preferred manner, in the present instance however,a pair of brackets 4 are provided, secured to a portion of the gatheringpool, and upon which is adapted to-rest the chamber portion 3. In orderthat the molten glass within the chamber may be delivered therefrom, aport or orifice 5 is provided preferably within the bottom of thechamber portion 3 andpreferably adjacent theouter end thereof. A block6, formed preferably of clay or other heat resisting material, andprovided with a vertically disposed opening 7, is positioned within thechamber portion 3 with the said opening 7 in register with the opening 5in the bottom of the chamber. A laterally disposed opening 8 is providedin the block 6 establishing communication between the glass containingchamber and the opening 7, while the opening 7 adjacent its upper endisflared as at 9 in order to receive a flame jet 10. To control the flowof molten glass through the laterally disposed opening 8, a gate 11 isprovided, which is constructed to form a foot 12, adapted when incontact with the walls of the block 6 to exclude molten glass from theopening 8, and is provided with an outwardly extending body portion 13,provided with a threaded stem 1(1 for the reception of an in.

ternally threaded adjusting wheel 15 in order that the gate may be movedinto and out of engagement with the wall of the block 6. The outer endof the body portion 13, in order to reduce friction, is mounted uponrollers 16 mounted in a suitable supporting block 17 upon a bracket 18;the said bracket 18 being provided with a vertical extension 19 throughwhich-the threaded extremity 14. of the gate is projected, and whichco'iiperates with the adjusting wheel 15 to control the movement of thegate. Cooperating with the port or orifice 5 inthe bottom of the glasscontaining chamber, is a nozzle 20., This nozzle may be constructed ofany desired material, clay being found in general practice to beextremely efli'cient for the purposes, and is arrangedv as is shownclearly in Fig. 3 to provide a lip 21 extending into the passage assumedby the flowing glass. As shown in the present instance this isaccomplished by providing the nozzle 9 with an arcuate port, and thelowermost walls of the port being substantially longer than theremaining portion, in order that the chamber, and may be secured theretoin any preferred manner, brackets 23 being employed in the presentinstance, to engage shoulders 23 thereon.

' In order that the primary object of my invention may be successfullyattained, that is. the delivery of molten glass direct from thefurnaceto the -mold without the employmentof ladels 'orother manuallyoperated instruments, the 'mold. illustrated conventionally at 24 isarranged beneath the glass containing chamber and in direct verticalalinement with the outlet or discharge opening therein. It will beobvious from this construction that upon opening the gate 11, glass willbe permitted to flow tothe mold "through the ports 8, 7, and the nozzle20. In the downward movement of the glass through the opening 7, the lip21 which extends, as is illustrated, into the path of the downwardlyflowing metal, will obstruct and detain the molten mass sufliciently todeliver to themold a stream of uniform volume. Thus it will be seen thatthere'will be no diificulty experienced when it is necessary to directthe stream into molds having comparatively small orifices. By theprovision of the flame jet in the flared end of the opening 7, the glassflowing from the chamber will be kept in fluent condition, and preventedfrom becoming stiff orchilled. Also when the valve gate 11 is closed toexclude the molten mass, the passage 7, as well as the mouth 22 of thenozzle, will be kept free from the accumulation of glass.

In order that the string of glass flowing to the mold may be severed topermit of p the blowing process, shears 25 are provided, with thecutting edges thereof so positioned as to lie in the path of thedescending stream of glass. It is preferred that the cutting device beactuated mechanically, and to this end an air tank 26 is provided,mounted upon a suitable support 27, and is provided with a piston '28,to which is. se-

vprovided with a bracket 31, to which is connected, throughthe togglearrangement 32, the rear end of the shear blades forming the cuttingelement. In order that vertical adjustment of the shears relative to themold 24 and nozzle 20, maybe made, the pivot 33 of the shear blades isextended and threaded into a bracket 34 secured to the s'upport27, acoil spring 35 being interposed between the bracket 34; and the shearblades in order that the latter may at all times be held into frictionalengagement with each other. Each of the shear blades is provided with awater jacket 36 in order thatthe same may be kept in substantiallycooled condition in spite of the intense heat incident to the cuttingoperation, and water may be supplied and exhausted from these jackets bythe ducts 37. A'lug 38 is provided upon one of the shear blades toprevent the end of the cut string of glass from becoming deflected tofall outside of, or upon the edges of the mold, and obviously thelocation of such lug would be upon the under surface of one of the shearblades and at such longitudinal point thereon as to be in verticalalinement with the downward flow of the molten glass. From thedescription it will be obvious that when glass has flowed from theoutlet in suflicient quantity to be used in the mold, the operation ofthe shears is brought about to sever the stream. By the adjustment ofthe shears vertically with relation to the nozzle 20, it will be obviousthat the glass flowing from the nozzle may be allowed to assumedifferent shapes, that is, when the shears are adjusted close to the lipof the nozzle, the shears' in cutting the glass therefrom allow the sameto assume the shape of a ball in dropping into the mold. When the shearsare in lower position the glass will be permitted to string out, theadvantage of which will be apparent as when used in connection with anarrow necked .mold. This arrangement obviously eliminates the use of afunnel heretofore employed in introducing glass to the interior of moldsprovided with narrow necks.

In Fig. 5 of the drawing is illustrated a slightly modified form of thedevice. In this form there is shown the gathering pool or receptacle 2,and the chamber portion 3, both as illustrated in the preferred form,provided in this instance with a cover 39. In order that the gate may beoperated through the cover to control the flow of molten glass to theoutlet, it is obvious that an arrangement must be provided differentfrom that illustrated in the above described form, and to this end avertically adjustable gate 40 is arranged to slide through an opening inthe cover 39, and which is adapted to seat as at 42 upon an outwardlyextending seat portion of the block 43, the block 43, it might be herestated, is adapted to be used in the same capacity as the block 8 in thepreferred form. The upper or outwardly extending end of the gate 40, isprovided with a rod or bar 44, to the outer extremity of which ispivotally connected a pivoted link 45, being in connection at itsopposite end with a threaded bar and hand wheel 46 and 47 respectivelyfor controlling the movements of the gate 40. In this form there is alsoillustrated a slightly modified form of outlet, in which the opening5-in the bottom of the receptacle is angularly disposed in order thatthe glass in its downward movement will be prevented from adhering tothe wall 48, and thereby prevent'stringing or dripping of the glass uponpassing from the nozzle. Flame jets 49 and 50 are provided in the cover39 and adjacent the outlet respectively, in order that the glass will atall times be in a thoroughly fluer" condition.
